...represent any binary relation (if you chose binary matrix representation I'd recommend using BitSetVector data structure found in include/llvm/ADT directory). FYI, in linear scan register allocator EquivalenceClasses object is used to divide register classes via "alias" relation. See ComputeRelatedRegClasses method in RegAllocLinearScan.cpp. Anton. -------------- next part -------------- An HTML attachment was scrubbed...

Can someone explain the terminology used in the Doxygen comments for EquivalenceClasses? Specifically, what is a "Leader" as opposed to other members of an equivalence class? Say, for example, I want to create a set of equivalence classes to specify subset relationships. Imagine B is a subset of A, C is a subset of B, E is a subset of D and D has no relation to any other set. I'd
